A new megastigmane palmitate, 9-oxomegastigm-5(13)-ene-2 beta-palmitate (1), and a new oleanane triterpenoid, (3 beta)-3,23,28-trihydroxyolean-12-en-11-one (2), together with three known oleanane-type triterpenoids, beta-amyrin (3), erythrodiol (4), and (3 beta)-olean-12-ene-3,23,28-triol (5), were isolated from the aerial parts of Aster yomena (Asteraceae). Their structures were identified based on 1D- and 2D-NMR analysis, including 1H,1H-COSY, HSQC, HMBC, and NOESY techniques.
